Description

Technical Field

[0001] This utility model relates to the field of lubricating oil spraying technology, specifically a centralized dry oil lubrication system with a circulating filter device. Background Technology

[0002] In modern industrial production, the reliability and lifespan of key moving parts such as bearings, gears, and slide rails in large, heavy-duty equipment such as metallurgical rolling mills, mining crushers, cement rotary kilns, port cranes, and wind turbine generators directly determine the safe operation efficiency and maintenance costs of the entire production line. Dry grease centralized lubrication systems, as a key technology to ensure the stable operation of these devices under harsh conditions such as heavy loads, low speeds, impacts, dust, and humidity, have been widely applied. The basic working principle of a traditional dry grease centralized lubrication system is to pressurize the grease in the storage tank using a lubrication pump, and then deliver it to various dispersed lubrication points in a timed and quantitative manner through the main pipeline and distributor. The newly introduced grease forms an oil film at the lubrication point, squeezing out previously used, deteriorated, or impurity-contaminated old grease from the seals, completing one lubrication cycle.

[0003] In the circulating filtration systems mentioned or conceivable in the background art, heating devices, such as electric heaters, are usually fixedly welded or flanged inside the filter tank or pipeline. Once the heating element fails due to dry burning, aging, or damage, the entire filter unit or even the pipeline system may need to be shut down, emptied, and disassembled for repair or replacement. This process is not only time-consuming and labor-intensive, causing the equipment to be shut down for a long time, but also requires professional personnel to operate, resulting in extremely high maintenance costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 6The dry oil centralized lubrication system with circulating filtration device in this embodiment includes a workbench 1, which is a robust planar structure that supports all other components of the system. Multiple first supports 2 are connected to the bottom surface of the workbench 1. A residue tank 3 is connected to the workbench 1, and waste oil after lubrication drips into the residue tank 3. Multiple placement plates 21 are connected to the inner wall of the residue tank 3, and multiple first threaded sleeves 23 are connected to the outer wall of the residue tank 3. A first threaded block 24 is threadedly connected to the inner wall of each first threaded sleeve 23, and the outer wall of each first threaded block 24... Each of the first threaded blocks 24 is connected to a handle 25. Each first threaded block 24 has a connecting groove 26 inside. Each connecting groove 26 has a heating rod 27 connected to its inner wall. The heating rod 27 is activated to heat the waste oil collected in the residual tank 3 until its fluidity meets the pumping requirements. Each heating rod 27 has a placement groove 30 inside. Each placement groove 30 has a heating core 28 connected to its inner wall. Each heating core 28 has a second threaded sleeve 29 connected to one end. Each second threaded sleeve 29 has a second threaded block 31 threadedly connected to its inner wall.

[0017] The workbench 1 is connected to multiple second supports 8, and multiple second supports 8 are connected to a support plate 9. The support plate 9 is connected to a main oil tank 13, and the main oil tank 13 is connected to an oil injection pipe 12. Sufficient dry oil is added to the main oil tank 13 through the oil injection pipe 12. The support plate 9 is connected to a filter box 10. The heated low-viscosity waste oil is pumped into the filter box 10. The outer wall of the filter box 10 is connected to a fifth pipe 22. The end of the fifth pipe 22 away from the filter box 10 passes through the main oil tank 13 and extends into the interior of the main oil tank 13.

[0018] The support plate 9 is fixedly connected to a second support 15 on its bottom surface. The inner wall of the second support 15 is fixedly connected to a second oil pump 16. The second oil pump 16 acts as an oil supply pump, drawing clean dry oil from the main oil tank 13. One end of the second oil pump 16 is connected to a third pipe 14. The end of the third pipe 14 away from the second oil pump 16 passes through the support plate 9 and the main oil tank 13 in sequence and extends into the interior of the main oil tank 13. The other end of the second oil pump 16 is connected to a fourth pipe 32. The end of the fourth pipe 32 away from the second oil pump 16 is connected to an oil distribution block 17. The bottom surface of the oil distribution block 17 is connected to multiple nozzles 18. The oil distribution block 17 acts as a collector, evenly distributing a single stream of oil to the multiple nozzles 18 below, thereby achieving synchronous or quantitative supply to multiple lubrication points.

[0019] The workbench 1 is connected to a first support 5, and the inner wall of the first support 5 is connected to a first oil pump 6. The first oil pump 6 acts as a recovery pump, which draws heated waste oil from the bottom of the residue tank 3 through a first pipe 4. One end of the first oil pump 6 is connected to the first pipe 4. The end of the first pipe 4 away from the first oil pump 6 passes through the residue tank 3 and extends into the interior of the residue tank 3. The other end of the first oil pump 6 is connected to a second pipe 7. The end of the second pipe 7 away from the first oil pump 6 passes through the support plate 9 and the filter box 10 in sequence and extends into the interior of the filter box 10.

[0020] The outer wall of the filter box 10 is provided with multiple mounting slots 33. The inner wall of one mounting slot 33 is connected to a coarse filter plate 19 to intercept larger metal shavings, dust, fibers, etc. The inner wall of another mounting slot 33 is connected to a fine filter plate 20 to remove finer abrasive particles and contaminants. The outer walls of the coarse filter plate 19 and the fine filter plate 20 are connected together by a connecting plate 11.

[0021] The working principle of the above embodiment is as follows: The operator injects new dry oil into the main oil tank 13 through the oil injection pipe 12, and starts the second oil pump 16 to work. It draws dry oil from the bottom of the main oil tank 13 through the third pipe 14. After the dry oil is pressurized, it is transported to the oil distribution block 17 through the fourth pipe 32. The oil distribution block 17 evenly distributes the high-pressure dry oil to multiple nozzles 18 at its bottom, spraying it onto the lubrication parts of the workpiece or equipment located on the placement plate 21 in the residual tank 3. Excess dry oil will drip from the workpiece and collect in the residual tank 3 below. The operator can turn the handle 25 to drive the first threaded block 24 to screw in or out of the first threaded sleeve 23, thereby fixing the entire heating device to the side wall of the residual tank 3 and making it extend into the waste oil. After the heating rod 27 is powered on, its internal heating core 28 begins to heat up. The heat is conducted to the waste oil in the residual tank 3 through the heating rod 27. The heating core 28 is fixed to the placement plate 21 of the heating rod 27 through the second threaded sleeve 29 and the second threaded block 31. The design of the placement tank 30 facilitates the replacement of damaged heating core 28. When the waste oil is heated to a suitable viscosity, the first oil pump 6 is started. It draws the heated waste oil from the bottom of the residual tank 3 through the first pipe 4. The first oil pump 6 pumps the heated waste oil into the filter box 10 through the second pipe 7. The waste oil is purified in the filter box 10. The waste oil first flows through the coarse filter plate 19 to filter out larger metal shavings, dust and other solid impurities. The oil after coarse filtration then flows through the fine filter plate 20 to filter out finer particles and achieve a higher degree of cleanliness. The coarse filter plate 19 and the fine filter plate 20 are connected into a whole by the connecting plate 11 and installed in the mounting slot 33 of the filter box 10. When it is necessary to clean or replace the filter plates, the entire filter plate assembly can be easily pulled out. The clean dry oil after two stages of filtration flows back to the main oil tank 13 through the fifth pipe 22 connected to the outer wall of the filter box 10, mixes with the new oil, and waits for the next lubrication supply.

[0022] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
